Hello, I want to create temporary teams, for like duels and stuff, but I have no idea how to do it. The only thing I did was create a HashMap<String, ArrayList<>> teammanager = new HashMap<String, ArrayList<>>(); I thought I could store who the teams in the ArrayList, or something, but I was wrong. Can someone help me through this, I should probably create a team object, but I don't know how to use it. What I'm wanting to do, is let the user create a Team (Its not forever, no need to save in the config), and allow them to invite and kick. It's pretty hard and I'm dumbstruck on what to do. Thanks for helping in advance!
